UWB Receiver Design

Chapter
Part of the SpringerBriefs in Electrical and Computer Engineering book series (BRIEFSELECTRIC)

Abstract

In this chapter, we present the design of an UWB receiver based on synchronous sampling that consists of a sampling mixer integrated with a local strobe-pulse generator and a baseband filter and amplifier.It is realized in a single circuit board using microstrip line, CPW, slot line, and coupled slot lines, and is compact and low cost. The receiver achieves a conversion loss of 4.5-7.5 dB (without baseband amplifier) and conversion gain from 6.5-9.5 dB (with amplifier) across a 5.5-GHz RF bandwidth, dynamic range of more than 50 dB, and low harmonic distortion in the baseband output signal. Its performance in down-converting signals is comparable to a commercial sampling scope, yet with much significantly smaller size and lower cost. The design of the strobe pulse generators for sampling applications requiring low PRF is also presented. Detailed design of the sampling mixer is described. Moreover, a distributed amplifier suitable for UWB receivers is discussed. The designed amplifier is characterized completely in the time domain under non-sinusoidal signal operation necessary for UWB applications. It has a highly linear transmission phase and produces amplified signals which resemble faithfully the input UWB pulses, demonstrating its suitability for UWB applications.
